Methodology has been established for the formation of
enantiomerically enriched α-amino acids using palladium-catalysed
allylic amination. The formation of enantiomerically enriched
allylamines has been achieved with high enantioselectivity. Oxidative
cleavage of the allylamines provides arylglycine and glutamic acid
derivatives. Additionally, enantiomerically enriched β-amino acids
have been prepared in high enantiomeric excess. Palladium-catalysed
asymmetric allylic substitution is used as the key synthetic
transformation.
利用钯催化的烯丙基胺化作用生成对映体丰富的δ-氨基酸的方法已经确立。以高对映选择性生成了对映体丰富的烯丙基胺。烯丙基胺的氧化裂解提供了芳基甘氨酸和谷氨酸衍生物。此外,还制备出了对映体丰度很高的δ-氨基酸。钯催化的不对称烯丙基置换是合成转化的关键。
